Feature Description
1. Auto focus can automatically adjust the focus according to the brightness
2. The specification design has a margin, and the specification can be guaranteed under the condition of 10 °C ~ 35 °C.
3. Positive feedback of past failure examples, thereby achieving a low failure rate.
Colorful features:
4. With the alternate scan function, both main and delayed scans can be displayed simultaneously.
5. Alternate amplifiers can display both standard waveforms and horizontally amplified (10x) waveforms.
6. All models are equipped with dedicated TV synchronization circuit.
